Opened: Jun 19, 2013
Severity: 3-Major

Symptoms

When using Clientless-mode 1 and 2 header and 401 response in an access policy, the 401 auth item returns 'Negotiate' instead of 'Fallback', and does not issue a 401 prompt.

Impact

Access policy does not issue a 401 prompt.

Conditions

Using Clientless-mode 1 and 2 header and 401 response in Access Policy.

Workaround

For Clientless-mode 1 and 2, use an iRule to set the Authorization header so that no 401 is required. For Clientless-mode 3 does respond with 401, so, do not use Clientless-mode 3 that expects 401.

Fix Information

None
